JAMES R. STEELE, JR, OF OWEGO, NEW YORK, ASSIGNOR TO CHAMPION WAGON COMPANY, INCL, OF OWEGO, NEW YORK, A CORPORATION OF NEW YORK.

I'JUMPING-WAGDN.

To all whom i may concern:

Be it'known that ll, Janus R. Srnunn, din, a citizen of the United States, residing at Uwego, in the county of Tioga and State of New York, have invented certain new and useful Improvements in Dumping-Wagons, of which the following is a specification.

This invention relates to wagons and particularly to dumping wagons of the dropbottorn type, and provides a structure where by one of the drop doors is caused to close slightly in advance of the other to permit the 'use oi a cover strip or lap strip to prevent leakage between the doors.

Various devices have heretofore been proposed to accomplish this result, but these are commonly cumbersome and complicated and therefore are not particularly suited to the class of service required of them.

By my invention, a structure is produced which is simple in form and operation and may be quickly repaired or adjusted, if necessary.

A wagon body showing my invention applied is illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view showing the device as it appears with the doors of the wagon open; Fig. 2 is a vertical longitudinal section of a wagon in the position shown in Fig. 1; Fig. 3 is a rear elevation of a wagon body showing the position assumed by the various parts when the doors are partially open; and Fig. 1]: is similar to Fl 3 but shows the positions assumed when the doors are closed, certain parts being broken away to give a clearer view.

In the drawings, 1 represents the body 01'. the wagon, and 2 the rear axle of the same. The doors 3 and a are hinged to the body at the sides as at 5, the forms of the various parts above enumerated being essentially identical with those in common use in this type of wagon. The door 3 is provided with a cover or lap strip 6, and because of this strip it is necessary to close the door 3 in advance of the door l.

Each door carries a sill 7, at the edge remote from the hinge, and chains 8 and 9 passing through guides 10, carried by these sills are wound upon a drum 11, to draw the doors closed. The drum 11 is operated by a ratchet lever 12, in the manner well known in such wagons. This ratchet mechanism forming no part of the present invention, is

indicated diagrannnatically in Fig. 2 and it is to be understood that any form of ratchet drum, or equivalent device capable of use for this purpose, might be availed of. y The chains 8 and 9 are each attached by shackles 13 to a pendant link 14-, pivoted on a bracket 15. This bracket 15 is mounted upon the rear of the wagon body, and at ap proximately the middle of the wagon. The chain 8 which is attached to the door 3 passes directly from the guide 10 on this door to the link 14. The chain 9, however, which operates the door 4. first passes over a guide roller or sheave 16, mounted in a frame, 17, the axis of the roller 16 being to one side of the center of the wagon, and at such a height that the chain S) passes horizontally or approximately so from the roller to its point of attachment to the link 141'. (See Figs. 3 and 4). In this manner the directions of pull of the two chains 8 and 9 upon the link 14- are at approximately right angles to each other, the chain 8 pulling very nearly in line with the link let and the chain 9 pulling at approximately right angles thereto.

When the drum 11 is released the chains are unwound and the doors are dropped to the position shown in Figs. 1 andv 2. The stresses exerted by the weight of the doors 3 and i. upon their respective chains 8 and 9 are practically equal. Therefore the pulls exerted by these two chains upon the link let are also practically equal, but the chain 9 has a greater moment arm about the pivot 15 as will be readily appreciated and consequently draws the link 14 to the right, as illustrated in Fig. 1, and. also in Fig. 3 in which the doors are shown partially closed. Thus so long as simply the weight of the doors is acting upon the two chains the link 14- will be drawn to the right and the chain 9 will consequently be slightly increased in length. However, as soon as the door 3 has reached a closed position, additional stress placed upon the chain 8 will tend to draw the link 141- and the chain 8 into alineinent drawing the slack out of the chain 9, and thereby bringing the door .1: to a closed position. This, however, does not take place until the door 8 is entirely closed and there fore this door must always come to its closed position somewhat in advance of the door i. The chains are so adjusted that in the closed position of the door as indicated in Fig. 4.- the link 14 and the chain 8 will not draw into alinement butwill preserve a slight angularity as shown in the figure.

By means of the shackles 1.3 the chains 8 and 9 may be adjusted to the proper lengths and correction may thus be made for stretch and wear. Obviously any equivalent mode of attachment, permit-ting ready adjustment might be used.

While I have described and shown in some detail a particular form of wagon and a particular location of cover strip 6, it will readily be understood that these might be varied and that the essence of the invention is the mode of causing one door to close in advance of the other in the manner and by the means set forth regardless of the detailed construction of the wagon, or its parts. Therefore many changes in details can be made without departing from the spirit and scope of theinvention. For instance, while I show a rigid, one piece link 14, the form of this might be changed variously, as in effect it is merely a continuation of the chain 8, the particular form shown being adopted for its simplicity and cheapness of manufacture.

Having thus described the invention, what I claim is 1. The combination of a wagon body having doors; a link pivotally connected at one end to the wagon body; a guide attached to the wagon body to one side of the link; operating chains, one for each door, each connected to the free end of the link, one chain passing directly from its door to the link, the other passing around the guidebetween the door and its connection to the link, whereby the second chain pulls in a direction transverse to the normal line of pull of the link and the first chain; and means for drawing in the chains to close the doors.

2. In combination with a wagon body;

wagon body and adapted to cause the other chain to pull in a direction transverse to the first chain and said pivoted member.

3. The combination of a body; a pair of doors hinged at their outer edges to the body, one of said doors having a portion adapted to overlap the other; chain guides on the doors; a chain guide on the body; a chain winding mechanism; a pair of chains extending therefrom and through the chain guides on respective doors, one of said chains terminating in an inelastic extension link-portion pivoted to the body and the other chain passing around the guide on the body and being connected to the first chain at its point of junction with the extension link-portion.

4. The combination of a wagon body having doors; guides on the doors; operating cables passing through said guides; an extension connected to the ends of both cables and pivotally connected to the wagon body; a guide on the wagon body located to one side of the normal line of pull of one cable and said extension and adapted to guide the other cable to cause it to pull in a direction transverse to said normal line of pull; and mechanism for drawing in the cables.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
